3004.90.92.66 - Containing hydrochlorothiazide or its salts

This HTS category, 3004.90.92.66, specifically classifies medicaments that are prepared for therapeutic or prophylactic uses and contain hydrochlorothiazide or its salts. These products are presented in measured doses or retail packaging, aligning with the broader scope of heading 3004 which covers a wide range of pharmaceutical preparations. The presence of hydrochlorothiazide is the definitive criterion for classification under this code, indicating its primary therapeutic function.

This classification is distinguished from its sibling category, 3004.90.92.63, which covers medicaments containing furosemide and its salts. While both hydrochlorothiazide and furosemide are diuretics, their distinct chemical compositions and pharmacological profiles necessitate separate HTS classifications. Category 3004.90.92.68 encompasses all other medicaments within this specific subclass that do not contain either hydrochlorothiazide or furosemide.

As a leaf node, this category does not have further subcategories. Therefore, classification hinges directly on the presence of hydrochlorothiazide or its salts within the medicament, assuming it meets the other criteria of heading 3004, such as being in measured doses or retail packaging for therapeutic or prophylactic use. Examples would include tablets or capsules specifically formulated with hydrochlorothiazide for treating conditions like hypertension or edema.
